Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to an operating handle and an intravascular shockwave therapy device. Background Technology
[0002] Due to abnormal lipid metabolism, lipids in the blood are deposited on the originally smooth inner lining of blood vessels, gradually accumulating into atherosclerotic lipid plaques. Over time, these plaques increase in number and may even calcify, causing narrowing of the blood vessel lumen, obstructing blood flow, leading to ischemia in downstream blood vessels and the body, and producing corresponding clinical manifestations. Shockwave therapy is needed to break up and remove the calcified plaques.
[0003] Common vascular shockwave therapy devices consist of a main unit connected to a control handle via a cable. A catheter extends from the handle into the blood vessel, and the surgeon performs the procedure by gripping the handle. However, the cable length is limited. If the generator is improperly positioned, it can restrict the surgeon's range of motion when operating the handle, making it less flexible when treating large areas or areas requiring frequent movement. In multi-device treatment environments, the cable may also become entangled with cables from other devices, affecting ease of operation and potentially leading to device displacement or cable damage. Summary of the Invention

[0019] The technical solution in this application embodiment is to solve the problems mentioned in the background art above, and the general idea is as follows:
[0020] Please see Figure 1-4An operating handle includes a handle body 10 and an electrically powered winding mechanism 20. The winding mechanism 20 is installed at the tail of the handle body 10, and a cable 30 is provided at the end of the handle body 10. The cable 30 is wound onto the winding mechanism 20. A control lever 40 is provided on the winding mechanism 20 and electrically connected to it. A finger sleeve 50 is fixedly connected to the head of the control lever 40. During surgery, the handle body 10 is held with one hand, and the little finger is inserted into the finger sleeve 50. The index finger and thumb can control the handle body 10, while the movement of the little finger can control the winding mechanism 20. This avoids the influence of an unsuitable cable length, and the movement of the little finger will not interfere with the operation of the handle body 10. The finger sleeve 50 is also designed to prevent it from easily slipping out of control.
[0021] Please see Figure 1-4 The winding mechanism 20 includes a housing 21, which is detachably connected to the tail end of the handle body 10. A control rod 40 is fixed to the outer wall of the housing 21. Here, the control rod 40 is a rocker arm, and the movement of the finger can control the winding or unwinding of the winding mechanism 20, as well as the winding and unwinding speed. In this embodiment, the housing 21 is provided with a slot, and the end face of the handle body 10 is provided with a buckle. When the end face of the handle body 10 is pressed against the housing 21 and then rotated, the buckle is locked in the slot, forming a quick connection effect, which is convenient for disassembly, maintenance or storage.
[0022] Please see Figure 1-4 The winding mechanism 20 also includes a drum 22, which is wound around the outer wall of the housing 21 and is rotatably connected to the housing 21. Here, the cable 30 is a flat cable, which facilitates winding and reduces tangling and twisting, making it easy to use.
[0023] Please see Figure 1-4 The winding mechanism 20 also includes a motor 23. The stator of the motor 23 is fixedly connected to the housing 21, and the rotor of the motor 23 is fixedly connected to the inner wall of the drum 22. The motor 23 is electrically connected to the control rod 40. Here, a brushless motor 23 is used, which can precisely control the speed of the motor 23. Moreover, the motor 23 can be installed as a whole in the center of the drum 22, which is beneficial to the compact structure. A pulse width modulation circuit is set between the control rod 40 and the motor 23 to convert the action of the control rod 40 into a control signal for the motor 23. It should be noted that when the motor 23 unwinds, it is necessary to pull the cable 30 to prevent the cable 30 from unwinding prematurely in the housing 21 and affecting the rotation. In actual surgery, the cable 30 needs to be left slightly hanging so that its own weight is used as the power to pull the cable 30, which can avoid the need for manual pulling.
[0024] Please see Figure 1-4An annular groove is formed on the end face of the drum 22. A rotating seat 24 is rotatably connected to the inner wall of the annular groove. A slip ring 25 is provided on the rotating seat 24. An elastic brush 26 is provided on the inner wall of the drum 22 and is slidably connected to the slip ring 25. The brush 26 is electrically connected to the cable 30. The rotating seat 24 is circumferentially fixed to the housing 21. Here, the rotating seat 24 is circumferentially fixed to the housing 21 by interlocking. When the drum 22 rotates, the drum 22 and the rotating seat 24 rotate relative to each other. The brush 26 slides on the surface of the slip ring 25 to maintain electrical connection. The rotating seat 24 can remain relatively stationary with respect to the housing 21 and the handle body 10, which facilitates the electrical connection between the rotating seat 24 and the handle body 10.
[0025] Please see Figure 1-4 The end face of the swivel base 24 is provided with a socket 27, and the tail end of the handle body 10 is provided with a plug 11 that connects to the socket 27. Here, before connecting the handle body 10 to the housing 21, the plug 11 on the handle body 10 is first inserted into the socket 27 on the swivel base 24, and then the handle body 10 is inserted into the housing 21 and rotated. A quick connection is formed by using a snap and a slot. It should be noted that there is a flexible cable 30 between the plug 11 and the handle body 10 for easy connection.
[0026] Please see Figure 1-4 The control button on the handle body 10 has a head end, and the finger sleeve 50 is adapted to fit the little finger. Here, when holding the handle body 10, the index finger and thumb can control the control button on the handle body 10, while the little finger can be inserted into the finger sleeve 50 to control the operation of the winding mechanism 20.
[0027] Please see Figure 1-4 This utility model also provides an intravascular shockwave therapy device, including the aforementioned operating handle.
[0028] When using this application: Before connecting the handle body 10 to the housing 21, first insert the plug 11 on the handle body 10 into the socket 27 on the rotator 24, then press the end face of the handle body 10 against the housing 21 and rotate it. The buckle will then lock into the slot, forming a quick connection. When holding the handle body 10, the index finger and thumb can control the control button of the handle body 10, while the little finger can be inserted into the finger sleeve 50. By swinging the little finger, the control lever 40 can be deflected forward or backward, which can control the motor 23 to rotate forward or backward. The rotation speed of the motor 23 can be controlled by the angle of deflection. When the motor 23 rotates, it drives the drum 22 to rotate to realize the winding and unwinding of the cable 30. When the drum 22 rotates, the brush 26 slides on the surface of the slip ring 25 to maintain the electrical connection, so that the cable 30 and the handle body 10 are electrically connected.
[0029] In summary, during surgery, the handle body 10 is held with one hand, and the little finger is inserted into the finger sleeve 50. The index finger and thumb can control the handle body 10, while the movement of the little finger can control the winding mechanism 20. This avoids the influence of unsuitable cable length 30, and the movement of the little finger will not interfere with the operation of the handle body 10. The finger sleeve 50 is also not easy to get out of control.
[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
